5.5. MOUNTING
• Installation should be carried out by qualified and trained staff only.
• When connecting air ducts, consider the labels on the casing of the unit.
• Before connecting to the air duct system, the connection openings of ventilation unit should be closed.
• When connecting the ducts, the air-flow direction indicated on the device housing should be observed.
• Do not connect the bends close to connection flanges of the unit. The minimum distance of the straight air duct between the unit and the first
branch of the air duct in the supply air duct must be 1xD, in air exhaust duct 3xD, where D is the diameter of the air duct.
• It is recommended to use the brackets (accessories). This will reduce the vibration transmitted by the unit to the air duct system and environ-
ment.
• Sufficient space must be provided for opening of the manhole and filter covers.
• If the ventilation unit is wall-mounted wall, it may transmit noise vibrations to the premises. Though the level of noise generated by the fans is
admissible, mounting the unit it the distance of 400 mm from the nearest wall is recommended. Where this is not possible, mounting of the unit
on the wall of the room where the level of noise is not significant is recommended.
• Ducts are connected to the unit in such way that they could be easily disassembled and the heater could be removed from the unit when carrying
out maintenance, servicing and/or repairs
The protective film is used to protect the unit during transportation. It is recommended to remove the film; otherwise, oxidation
signs may occur.
